Brief summary
A prospective non-interventional cohort study at Erasmus MC of adult chronic HIV infected patients of ≥18 years of age who initiate antiretroviral therapy in routine care.
Detailed description
HIV cannot be cured with the current treatment armamentarium. A reservoir of latently HIV infected long lived CD4+T-cells is present in patients with HIV that are not affected by antiretroviral therapy. The evolution of this reservoir after therapy initiation is ill understood, as are the potential strategies to eradicate this reservoir. This study aims to anticipate on future HIV cure strategies by building a cohort to study ex vivo the reservoirs of HIV patients, the obstacles to cure HIV, and new therapeutic compounds and strategies. Main study parameters/endpoints: 1. Change in viral reservoir size after antiretroviral treatment initiation. 2. Evolution of phenotypical and functional aspects of the anti-HIV host immune responses. 3. Ex vivo activity of established and novel HIV latency reversing agents. 4. Variance in HIV reservoir and host immunity between HIV subtypes and clinical variables. A project from the Erasmus MC HIV Eradication Group (EHEG).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To develop a prospective cohort in the Netherlands of chronic HIV infected patients within-depth reservoir characterization for future cure interventions. | 5-10 years | The HIV latent reservoir will be characterised in chronic HIV patients using novel techniques like FISH-flow |
| To study the evolution of the HIV reservoir and immune host responses over time during antiretroviral therapy. | 5-10 years | The HIV reservoir will be characterised over time to study the dynamics of the reservoir |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To explore established and putative new interventions aimed at curing HIV. | 5-10 years | Blood and leucapheresis samples will be collected for testing of HIV cure drugs |
| To explore differences in reservoir size, activity and host responses, and their relation with clinical characteristics, between patients with different dominant HIV subtypes and sexes. | 5-10 years | Blood and leucapheresis samples will be collected for reservoir characterisation to compare reservoirs between patients |
| To compare and validate new reservoir assays with current established assays. | 5-10 years | Blood and leucapheresis samples will be collected to compare and validate new reservoir assays |
